Here's a small .php script that will display your content once each month for a few days, depending on the date and number of items to be rotated

Development logic

(Today's Date is 23)

Day number is 23

Number of articles is 9 -- # days in a month (31) divided by number of articles (9) gives number of days per article: 3.44444444444

Date divided by the number of days per article gives raw article# 6.67741935484

Rounded up article number to display is # 7

CONDENSED SCRIPT:

<?php $num_items = 4; $num_days = 31 / $num_items; $sl = ceil( date("d") / $num_days); include ('video_'.$sl.'.htm'); ?>

Set the $num_items = to the number of videos or articles you want to rotate. Make their file names look like this: video_1.htm, video_2.htm, etc.
